Red vomit. Red vomit is usually a sign that your dog is vomiting blood. If the blood is fresh (a normal shade of red), this could mean trouble with the lining of their stomach or possible inflammation; alternatively, vomiting blood could be a response to a poisonous substance.
If your dog vomits green, brown, or yellow liquid, it's usually harmless. But if your dog's vomiting red liquid, or even black vomit with a coffee-grounds appearance, it can mean bleeding from your dog's stomach or other parts of the GIT. This can be an emergency and you would need to contact your vet immediately.
Clear, slimy or foamy vomit that's tinged with yellow indicates your dog's stomach was empty at the time vomiting occurred (the foam comes from mucus that's normally present in the stomach plus saliva, while the yellow is bile from the small intestine).
Vomited blood is easily recognizable when it is fresh, but if it is partially digested it often has a dark grainy appearance, similar to old coffee grounds. Any problem that erodes the lining of the stomach can expose blood vessels and cause gastrointestinal hemorrhage that will make your dog vomit blood.
If your dog's vomit includes pink foam, there may be some blood mixing in with it. This is not always a sign of a very serious condition, but it can be. Dangerous causes of blood in vomit include intestinal blockages, poisons, ulcers, and tumors, so it's important to investigate the situation.
Bloody (red or pink)
If your dog's vomit is pink and has no red, it's usually not an emergency medical situation. However, if there is red blood or clots, it could indicate bleeding in the stomach or small intestine, which could be a sign of: Ulcers.
Vomiting blood can be a serious issue for a dog, and it is important to seek veterinary care as soon as possible. It is best to consider this a medical emergency and to contact a veterinarian or an emergency animal hospital immediately. The sooner a dog receives treatment, the better the chances for a full recovery.

If when your dog vomits that one time, they are bringing up blood, dark brown/black vomit, it smells like poo or you know they have eaten something potentially toxic, then contact your vet immediately for further advice. The same goes if your dog appears unwell or in pain at all.
There are a few characteristics that many pet owners notice with parvo vomit. Your puppy may initially vomit food, but it'll soon turn to liquid vomit when they are no longer able to keep any food or even water down. Parvo vomit is often yellow or brown in color, and may even contain blood or foam.
Vomit may be clear or a yellow or brown color, and diarrhea will often contain blood and be a light yellow or mustard colored hue. In addition to vomiting frequently, your puppy may also appear to be drooling or foaming at the mouth as part of their parvo symptoms. Your puppy's nose may also begin running.
If vomiting happens repeatedly or diarrhoea persists for more than two days, consult your vet. Even if your dog is no longer being sick, you should contact your vet if they are not eating or are depressed or lethargic. Puppies are particularly vulnerable so take yours to the vet right away if they are sick.
Clinical signs of poisoning in a dog may include: Gastrointestinal signs: vomiting, diarrhea, extreme salivation, loss of appetite, and nausea or dry heaving. Internal bleeding: indicated by pale gums, a racing heart, coughing up or vomiting blood, weakness or lethargy, or a dog's falling over or collapsing.
The frothy bright yellow look of early stages of dog vomit slime mold makes it look like scrambled eggs. But it's not edible. Mushrooms are a lot like plants, but they lack chlorophyll and have to take nutrients from other materials.
Signs of Sepsis
When sepsis does develop, signs include shaking, fever, weakness, confusion, lack of appetite, vomiting, and diarrhea. Other signs can also be present depending on the type and location of the initial infection.
Some bacterial infections caused by food poisoning, such as salmonella and E. coli, are common in young dogs or those with weak immune systems. In addition to vomiting blood, these infections may be accompanied by bloody diarrhea, loss of appetite, fever, and or fatigue.
However, if your dog vomits more than once within 24 hours, it could be a more serious issue that needs medical attention. Look for other symptoms that are cause for concern, including signs that they feel down, not eating or drinking for long periods of time, or having diarrhea.
Red or bloody vomiting is also called hematemesis. It usually appears pink to bright red, and in some cases, it may also look dark brown or black. A person should immediately consult a doctor if they experience pink, red, or bloody vomit.
Hematemesis is a sign of internal bleeding from the upper portion of your digestive tract — the esophagus, stomach and first portion of your small intestine called the duodenum. If you're vomiting blood, you should seek medical attention right away.
If your dog is vomiting orange, it is usually diet-related, veterinarians say. However, “in some cases, blood in the vomit could appear orange when mixed with yellow coloration,” says Satchu. If you can't pinpoint a food-related cause for orange dog vomit, it's a good idea to schedule a visit with your veterinarian.
If your dog is throwing up, but still acting otherwise normal, it's possible that your pet has either chronic gastritis (inflammation of the stomach) or food indiscretion. Food indiscretion in dogs is very common when they get so excited about eating that they eat too fast or too much, and some of it comes back out.
